In 1975, cousins Cheng Qingwu and Cheng Qingwei are reborn from their miserable past lives, both returning to three days before their weddings. Faced with the two men who had driven them into ruin, the sisters make a startling decision in the woodshed: they will switch grooms.
Cheng Qingwu chooses Lu Zhengyan, a young officer supposedly destined to die in battle. She is determined not only to change his fate, but also to build a career of her own, starting with her embroidery in the army family compound and carving out a place for herself in the cracks of the times. Cheng Qingwei grits her teeth and marries Shen Yizhou, a rural young man with nothing to his name. Putting vanity aside, she draws on the shrewdness she accumulated in her past life to help him get started repairing tractors. Together, they ride the wave of reform and opening up, until she becomes the most reliable partner in his business empire.
From then on, one steadily builds her footing in the army, stitching a brand legend with her needle; the other rides the tides of the business world, using her ledgers to chart a commercial empire. They survive trials of life and death and the threat of bankruptcy, sharing resources and supporting each other. This is not simply a story of switching husbands and turning their lives around. It is the story of two women reborn who use their wisdom and courage to break free of fate’s shackles amid the tide of the times, flourish side by side in their respective careers, and ultimately grow into towering trees who help each other thrive while shining in their own right.
